Abstract
Abstract A car seat table is designed for securement on a horizontal seat portion of a rear vehicle seat utilizing a conventional central seat belt. An upper and a lower tray are secured in spaced parallel relation by a frame formed from rigid tubular members. A pair of circular openings are formed through the upper tray for supporting beverage containers. Removable inserts may be utilized to adapt the tray for use with various different dimensioned beverage containers. The inserts may include resilient radially inwardly extending fingers for engagement with and accommodation of various different diameter beverage containers. The upper tray preferably includes an upstanding peripheral rim and a central recessed area for containing various food and other items for use by back seat vehicle occupants. In a second embodiment, the upper and lower trays may be mounted for vertical adjustment between raised and lowered positions by a parallelogram linkage.

Claim 1
Independent Claim
128 words
A car seat table, comprising: an upper tray; a central recessed area formed on said upper tray; an upstanding peripheral rim on said upper tray, surrounding said central recessed area; at least one circular opening formed through said upper tray for receiving a beverage container; a removable insert having a reduced diameter opening dimensioned to be retained in said circular opening for use with different diameter beverage containers; a plurality of resilient radially inwardly extending fingers spaced around said insert for engagement with various different diameter beverage containers; an annular rim surrounding said circular opening in said tray for supporting said insert; a lower tray; an upper frame securing said upper and lower trays in parallel spaced relation, said frame formed by a plurality of rigid tubular members;
Claim 2
Dependent Claim

A car seat table, comprising: an upper tray; a central recessed area formed on said upper tray; an upstanding peripheral rim on said upper tray, surrounding said central recessed area; at least one circular opening formed through said upper tray for receiving a beverage container; a removable insert having a reduced diameter opening dimensioned to be retained in said circular opening for use with different diameter beverage containers; a plurality of resilient radially inwardly extending fingers spaced around said insert for engagement with various different diameter beverage containers; an annular rim surrounding said circular opening in said tray for supporting said insert; a lower tray; an upper frame securing said upper and lower trays in parallel spaced relation, said frame formed by a plurality of rigid tubular members;
Claim 3
Dependent Claim
129 words
a parallelogram linkage mounting said first and second trays for simultaneous movement in fixed relation between vertically raised lowered positions; said parallelogram linkage formed by four corner frame members each having a lower end pivotally mounted to corner portions of a fixed lower frame and an upper end pivotally mounted adjacent corner portions of said lower tray; two of said corner frame member dimensioned to receive a vehicle lap type seat belt in surrounding relation when in a vertical position; and said upper frame dimensioned for abutment with a vehicle seat back when in said raised position, whereby tightening of the vehicle seat belt will initially move said upper and lower trays to said raised position and will subsequently maintain said upper and lower trays in said raised position.
Claim 4
Dependent Claim
129 words
a parallelogram linkage mounting said first and second trays for simultaneous movement in fixed relation between vertically raised lowered positions; said parallelogram linkage formed by four corner frame members each having a lower end pivotally mounted to corner portions of a fixed lower frame and an upper end pivotally mounted adjacent corner portions of said lower tray; two of said corner frame member dimensioned to receive a vehicle lap type seat belt in surrounding relation when in a vertical position; and said upper frame dimensioned for abutment with a vehicle seat back when in said raised position, whereby tightening of the vehicle seat belt will initially move said upper and lower trays to said raised position and will subsequently maintain said upper and lower trays in said raised position.
